.Application :tiled June 24, 1918. Serial No. 241,572.

To aZZ whom tmay concern:

Be it known that l, SAMUEL P, Gnrinn'r, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful improvements in DoorLocks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved door lock, and has for its primary object to provide a locking device particularly designed for application to the doors of commercial vehicle bodies whereby the doors may be easily and quickly opened, while at the same time access to the interior ot the vehicle body by vunauthorized persons may be etfectually prevented.

tis another important object of the invention to provide a locking device for the above purpose which is so'constructed that the doors are locked bothl on the interior and the exterior thereof.

And ,it is a further general object of my invention to provide a door locking device the various elements of which are ot' simple and durable construction, effective and reliable in their operation and capable of being manufactured at relatively small cost.

With the above and other objects in view the invention consists in the improved combination, construction and relative arrange-` ment of the several parts as will be hereinafter more fully described, subsequently claimed and illustrated in the accompanying drawing in which similar reference characters designate the corresponding parts throughout the several views; and wherein:

Figure l is an exterior elevation showing my improved locking device in its applied position, portions .of the doors being broken away;

Fig. 2 is a' sectional view taken on the line 2 2 of Fig. 1;

Fig. 3 is a section taken on the line 3 3 of Fig. 1;

Fig. 4 is an end elevation ofthe operating lever and the keeper therefor, showing the lever locked.

Fig. 5 is a section taken on the line 5 5 Fig. 6 is a section taken on the line 6 6 of Fig. 1.

Referring in detail to the drawing, D and D indicate the two doors or' the motor, vehicle body, said doors at their outer vertical edges being pivotally or hingedly mounted upon the side walls of the lvehicle body in any approved manner for outward swing` ing movement. A balance 'strip 'S secured to the outer tace of the door D projects lat erally from the free vertical edge thereof for lapping engagement upon the outer face of the other door D as shown in F ig. 2, whereby when the door with the locking mechanism to be hereinafter described is locked in its closed position, the door D will likewise be held closed against outward swinging movement.

n the accompanying drawing wherein I have illustrated one preferred embodiment of my invention7 5 designates a. rod or shaft which is rotatabl Y mounted in a transverse opening d in the door D adjacent the free vertical edge thereof. The shaft 5 has v,a circular head 6 formed upon one ofits ends while the other end of said shaft is reduced in diameter as at? and formed withl athreaded terminal 8. A metal bar 9 is provided with an opening in receive the'shaft 5, said bar when the device is applied being interposed between the head 6 on said shaft and the face'of the'door D. This bar extends horizontally upon one side ot' the head 6 and is rigidly secured to the door by means of suitable screws shown at 10. The bar 9 is formed upon its rear 'face with a boss 11 surrounding the opening in the end of said bar through which `the shaft 5 is engaged. A pin 12 is inserted through a transverse opening in the shaft 5 and the projecting ends of thispin engage the boss 1l whereby the shaft is held ao'ainst axial shifting movement through the ar 9. The boss 11 and the pin 12 are disposed in a' countersink or recess 13 in the face of .the door. At its other end in a reversely curved hook-14 the bill or terminal of which is disposed in parallel relation to the body of the bar.

To the head 6 an operating bar or lever 15 is securely riveted as at 16. This lever is formed of spring steel and preferably tapers in width at one of its ends as shown in Fig. 1, said end of the bar being provided with a biol) or handle 17 having a' bifurcated shank 18.

The end portion-of the resilient bar or lever 15 which projects in the opposite direction from the head 6, an(` which is relatively short, has a transversely curved terniinal 20. When the bar or lever is ni ed D which is equipped' one of its ends toA the bar 9 terminates Pthe outer tace of the door D.

to a horizontal position, the longitudinal edges of this curved terminal are adapted for engagement vvith the body ofthe bar 9 while the convex surface of said terminal has bearing engagement against the inner 'face of the bill of the hook la. By thus transversely curving the terminal of the lever, it may more readily enter the hook lll and by its resilient bearing engagement at the outer edges and the medial portion thereof with the terminal hook ot" the bar 9, the levez` is more effectively held against vibration or relative movement vvhereby rattling and the noise incident thereto is obviated.

rI`he reduced inner end portion T of the `shait 5 is ot' rectangular or other polygonal shape in cross section and .upon the same a plate Q1 is engaged, said plate having a boss 22 projecting from one tace thereof which will allovv for varying thickness ot doors by reversing said plate and against the end ot which a retaining nut threaded on the terminal 8 of the shaft is adapted to engage, said nut holding the plate 2l against the shoulder T at the inner end of the reduced portion 7 of the shaft which is disposed in spaced relation to the inner Jface of the door. The ends otl the plate 2l projecting in opposite directions from the central boss provide arms in which the bolts 2l are engaged. designates the locking rods ivhich are flattened at one ot' their ends and provided with openings therein to receive.

the bolts Q4. uts 2G are threaded upon the bolts 24 to retain the locking rods in connection with'said bolts. The rods 25 extend vertically and are loosely movable through the openings 29 provided in the angular ends QS ot the guide members 27 which are fixed to the inner face ot' the door at its upper and lower edges. These rods are adapted for engagement in suitable sockets or keepers indicated at 30.

1 have also provided means whereby the actuation of the bar or lever l5 by unauthori'fied persons may be prevented and the doors locked exteriorly thereof as Well as upon the interior. This means as herein shown consists in a keeper generally indicated by the numeral 31, said keeper being in the torni of an elongated U-shaped plate, one arm 32 of which is adapted to be secured to The other arm of this keeper plate, designated is vertically disposed and has a slot 34e therein opening upon the upper edge of said arm. At each side of this slot, the upper edge of the arm is inwardly turned or bent to provide angularly disposed lips lVhen the lever 15 is moved to its locking position, the biturcated shank 1S of the handle or knob l? moves downwardly into the slot 84, the end of the lever being sprung inwardly toward the tace ot the door so that the lever bar vvill move downwardly between the lips moeite 35 and the arm 32 of the keeper. hen the inward Yiressure on the lever bar is released, said bar vvill spring outwardly, owing to its inherent resiliency, against the inner side of .ther keeper arm 33 and beneath the inwardly projecting lips on the upper end of said arm. The hasp of a padlock may be novv engaged through the bifurcation of the shank 17 as indicated in Fig. l to securely lock the bar 15 to the keeper. 1n this manner, the operating lever for the locking bolts 25 may be securely locked against operation so that the doors cannot be opened by unauthorized persons. As the other end of the lever is operatively engaged in the hook ,li-

movementot the lever, the shaft 5 is rotated and through the medium of the plate '21 on the inner end of said shaft, the locking bolts 25 are vertically moved in relatively opposite directions and disengaged from the keepers 30. The doors D and D can then be swung outwardly to their open positions.

From the foregoing description taken in connection with the accompanying drawing. the construction, manner of operation and several advantages of my improved locking device Will be clearly and fully understood. lVhile the invention is primarily designed with a view to providing a simple and effective locking means for the doors of commercial vehicle bodies, it is of course manitest that the device can also be advantageously employed for various other analogous purposes. The parts of the improved door lock can be readily assembled and applied in operative position, Without necessitating any material alterations in the doors of the vehicle body construction. A device constructed and operating in the manner described provides easilv and quickly operable means for securely locking the doors in closed position upon both the interior and exteriorthereof. As no springs or other easily breakable elements are employed, the device is not liable to get out of order, but on the contrary, the various parts being of simple form, the invention as a Whole will be highly durable and serviceable in practical use.

lllhile I have herein shown and described the preferred construction and relative arrangement of the several elements, it is to be understood that the device is susceptible 0I" considerable moeiee'ien hereiii, emi there'f'ere reierfe he privihge e :iii Sueh `iegiinme changes z e emhmieei within the spirit sind Seepe eL i ,invention :is: claimedh Ewing thus describe@L my ii1\'eziiien,wimt einim isz* l.
